CIFA-1, the first Romanian computer
CIFA is the acronym for "Calculatorul Institutului de Fizică Atomică" (English: Computer of Atomic Physics Institute).
CIFA-1, the first Romanian computer, was built in 1957 under the guidance of Victor Toma.[1] The experimental first-generation model CIFA-1 was reproduced in small numbers both in the original variant with vacuum tubes as well as in two variants using transistors: CIFA-10X and CET 500.[2]
CIFA-1 made Romania the second socialist country (after USSR) and eighth overall to build an electronic computer.[3][4]

CIFA-1
CIFA-3
The logic designs for CIFA-1 started in 1953, at the Academy Physics Institute in Măgurele, with Victor Toma as the head of the project.[1][3] It was presented at the International Symposium in Dresden in 1955, and the prototype, which used 1500 vacuum tubes, a cylindrical magnet memory and machine code programming, was finished in 1957. Its size was that of three wardrobes, it had a paper tape input and a typewriter output and was able of solving 50 operations per second.[5][6]
CIFA-1 was in use for two years. After it was decommissioned, it was scrapped and no part of it survived today.[6][7]
Later computers
Later CIFA computers were CIFA-2 (800 vacuum tubes) in 1959, CIFA-3 (for the Bucharest University's Computer Center) in 1961 and CIFA-4 in 1962.[1] Other Romanian computers of the era are MECIPT and CETA at the Polytechnic Institute of Timișoara, MARICA, DACICC-1 and DACICC-200 at the T. Popoviciu Institute of Numerical Analysis, Cluj-Napoca.[2][3][5][8]
VITOSHA was the first Bulgarian computer, built in 1962-1963 on the basis of a cultural agreement between the Romanian and Bulgarian Academies of Science. It was based on CIFA-3.[3][5]
